[SebastianVonRotz]

Is your feature request related to a problem? Please describe.
The sorting of documents is create for "title", "link" and "description" but not for "category" and "forward"

Describe the solution you'd like
Being able to additionaly sor the " category"

[janikvonrotz]

I have enabled sorting for "forward".

Sorting "category" is a bit more difficult. To put it simply everything that is a refrence f.g. documents -> category or user -> tenant cannot be sorted in the database.

However, I could create a client sorting. So if you really require this feature I could implement it.
